1. A refuse vehicle comprising:
a chassis;
an energy storage device supported by the chassis and configured to provide electrical power to a prime mover, wherein activation of the prime mover selectively drives the refuse vehicle;
a vehicle body supported by the chassis, the vehicle body including an on-board receptacle for storing refuse therein;
an electric power take-off system positioned on the vehicle body, the electric power take-off system including an electric motor configured to drive a hydraulic pump to convert electrical power received from the energy storage device into hydraulic power, wherein an amount of electrical power at least one of received by and provided to the electric motor is limited by a controller to control an output characteristic of the hydraulic pump; and
a hydraulic component in fluid communication with the hydraulic pump and configured to operate using hydraulic power from the electric power take-off system,
wherein the hydraulic pump is a swashplate-style variable displacement pump, and
wherein the controller controls the output characteristic of the hydraulic pump by activating a solenoid valve, wherein activating the solenoid valve selectively opens a flow path to introduce pressurized hydraulic fluid toward a swashplate of the hydraulic pump to adjust an angle of the swashplate.
